Question

# If an ideal pulley system can lift a load of 2000 N by an effort of 500 N. Find its velocity ratio.4

Solution

## The correct option is A 4Given, Load = 2000 N Effort = 500 N Mechanical advantage, (M.A) = LoadEffort=2000500=4 Efficiency = M.A.V.R. For an ideal pulley, the efficiency is 100% or 1. Hence, the velocity ratio, V.R.=M.A.=4
